“Doc!” she shouted.
Standing at the trailer door, Thorne caught the rope, and tied it around Malcolm. Malcolm groaned. “Let’s go,” Thorne said. He put his arm around Malcolm and swung them both out, until they were standing on the gearbox.
“Christ,” Malcolm said, looking upward. But Sarah was already pulling him, the rope tightening.
“Just use your arms,” Thorne said. Malcolm started to rise; in a few moments, he was ten feet above Thorne. Sarah was up on the cliff, but Thorne couldn’t see her; Ian’s body blocked his view. Thorne began to climb, his legs struggling for purchase. The underside of the trailer was slippery. He thought: I should have made it nonskid. But who would ever make the undercarriage of a vehicle nonskid?
In his mind’s eye, he saw the accordion connector, tearing . . . slowly tearing . . . opening wider. . . .
He climbed upward. Hand over hand. Foot by foot.
Lightning flashed, and he realized that they were close to the top.
Sarah was standing on the edge of the cliff, reaching down for Malcolm. Malcolm was pulling himself up with his arms; his legs swung limp, free. But he was still going. Another few feet . . . Sarah grabbed Malcolm by the shirt collar, and hauled him up the rest of the way. Malcolm flopped over, out of sight.
Thorne continued up. His feet slipped. His arms ached.
He climbed.
Sarah was reaching down to him.
“Come on, Doc,” she said.
Her hand was extended.
Fingers reaching toward him.
With a metallic whang! the mesh ripped on the connector, and the trailer dropped down ten feet, the coils widening.
Thorne climbed faster. Looking up toward Sarah.
Her hand still reached down.
“You can do it, Doc. . . .”
He climbed, closing his eyes, just climbing, holding the rope, gripping it tightly. His arms ached, his shoulders ached, and the rope seemed to become smaller in his hands. He twisted it around his fist, trying to hold on. But at the last moment he began to slip, and then he felt a sudden burning pain in his scalp.
“Sorry about that,” Sarah said, and she pulled him up by his hair. The pain was intense but he didn’t care, he hardly noticed, because now he was alongside the accordion connector, watching the coils pop free like a bursting corset, and the trailer dropped lower but she still pulled him, she was immensely strong, and then his fingers touched wet grass, and he was over the side. Safe.
Beneath them, there was a sharp series of metallic sounds—whang! whang! whang!—as the coiled metal rods snapped one after another, and then, with a final groan, the trailer broke all connection, and fell free down the cliff face, growing smaller and smaller, until it smashed on the rocks far below. In the glare of lightning, it looked like a crumpled paper bag.
Thorne turned, and looked up at Sarah. “Thanks,” he said.
Sarah sat heavily on the ground beside him. Blood dripped from her bandaged head. She opened her fingers, and released a handful of his gray hair, which fell in a wet clump onto the grass.
“Hell of a night,” she said.
The High Hide
Watching through the night-vision glasses, Levine said, “They made it!”
Kelly said, “All of them?”
“Yes! They made it!”
Kelly began to jump and cheer.
Arby turned, and grabbed the glasses out of Levine’s hand.
“Hey,” Levine said. “Just a minute—”
“I need them,” Arby said. He spun back around and looked out at the dark plain. For a moment, he couldn’t see anything, just a green blur. His fingers found the focus knob, he twisted it quickly, and the image came into view.
“What the hell is so important?” Levine said irritably. “That’s an expensive piece of equipment—”
And then they all heard the snarling. It was coming closer.
In pale shades of luminous green, Arby saw the raptors clearly. There were twelve of them, moving in a loose cluster through the grass, heading in the direction of the high hide. One animal was a few yards ahead and seemed to be the leader; but it was hard to discern any organization in the pack. The raptors were all snarling and licking the blood off their snouts, wiping their faces with their clawed forearms, a gesture oddly intelligent, almost human. In the night-vision glasses, their eyes glowed bright green.
They did not seem to have noticed the high hide. They never looked up toward it. But they were certainly headed in that direction.
Abruptly, the glasses were yanked out of Arby’s hands. “Excuse me,” Levine said. “I think I’d better handle this.”
Arby said, “You wouldn’t even know about it, if it wasn’t for me.”
“Be quiet,” Levine said. He brought the glasses to his eyes, focused them, and sighed at what he saw. Twelve animals, about twenty yards away.
Eddie said quietly, “Do they see us?”
“No. And we’re downwind of them, so they won’t smell us. My guess is they’re following the game trail that runs past the hide. If we’re quiet, they’ll go right past us.”
Eddie’s radio crackled. He hastily reached to turn it down.
They all stared out at the plain. The night was now calm and still. The rain had stopped, and the moon was breaking through thinning clouds. Faintly, they saw the approaching animals, dark against the silver grass.
Eddie whispered, “Can they get up here?”
“I don’t see how,” Levine whispered. “We’re almost twenty feet above the ground. I think we’ll be fine.”
“But you said they can climb trees.”
“Ssssh. This isn’t a tree. Now, everybody down, and quiet.”

Malcolm winced in pain as Thorne stretched him out on a table in the second trailer. “I don’t seem to have much luck on these expeditions, do I?”
“No, you don’t,” Sarah said. “Just take it easy, Ian.” Thorne held a flashlight while she cut away Malcolm’s trouser. He had a deep gash on his right leg, and he had lost a lot of blood. She said, “We have a medical kit?”
Thorne said, “I think there’s one outside, where we store the bike.”
“Get it.”
Thorne went outside to get it. Malcolm and Harding were alone in the trailer. She shone the light into the wound, peering closely. Malcolm said, “How bad is it?”
“It could be worse,” she said lightly. “You’ll survive.” In fact, the wound cut deep, almost to the bone. Somehow it had missed the artery; that was lucky. But the gash was filthy—she saw grease and bits of leaves mashed into the ragged red muscle. She’d have to clean it out, but she’d wait for the morphine to take effect first.
“Sarah,” Malcolm said, “I owe you my life.”
“Never mind, Ian.”
“No, no, I do.”
“Ian,” she said, looking at him. “This sincerity is not like you.”
“It’ll pass,” he said, and smiled a little. She knew he must be in pain. Thorne returned with the medical kit, and she filled the syringe, tapped out the bubbles, and injected it into Malcolm’s shoulder.
He grunted. “Ow. How much did you give me?”
“A lot.”
“Why?”
“Because I have to clean the wound out, Ian. And you’re not going to like it when I do.”
Malcolm sighed. He turned to Thorne. “It’s always something, isn’t it? Go on, Sarah, do your damnedest.”
* * *
Levine watched the approaching raptors through the night glasses. They moved in a loose group, with their characteristic hopping gait. He watched, hoping to see some organization in the pack, some structure, some sign of a dominance hierarchy. Velociraptors were intelligent and it made sense that they would organize themselves hierarchically, and that this would appear in their spatial configuration. But he could see nothing. They were like a band of marauders, shapeless, hissing and snapping at one another.
Near Levine in the high
hide, Eddie and the kids were crouched down. Eddie had his arms around the kids, comforting them. The boy especially was panicky. The girl seemed to be okay. She was calmer.
Levine didn’t understand why anyone was afraid. They were perfectly secure, high up here. He watched the approaching pack with academic detachment, trying to discern a pattern in their rapid movements.
There was no doubt they were following the game trail. Their path exactly matched the paras earlier in the day: up from the river, then over the slight rise, and along the back of the high hide. The raptors paid no attention to the hide itself. They seemed mostly to interact with each other.
The animals came around the side of the structure, and were about to continue on, when the nearest animal paused. It fell behind the rest of the pack, sniffing the air. Then it bent over, and began to poke its snout through the grass around the bottom of the hide.
What was it doing? Levine wondered.
The solitary raptor growled. It continued to root in the grass. And then it came up with something in its hand, something it held in its clawed fingers. Levine squinted, trying to see it.
It was a piece of wrapping paper from a candy bar.
The raptor looked up at the high hide, its eyes glowing. It stared right at Levine. And it snarled.
Malcolm
“You feel okay?” Thorne said.
“Better all the time,” Malcolm said. He sighed. His body relaxed. “You know, there’s a reason why people like morphine,” he said.
Sarah Harding adjusted the inflatable plastic splint around Malcolm’s leg. She said to Thorne, “How long until the helicopter comes?”
Thorne glanced at his watch. “Less than five hours. Dawn tomorrow.”
“For sure?”
“Yes, absolutely.”
Harding nodded. “Okay. He’ll be okay.”
“I’m fine,” Malcolm said, in a dreamy voice. “I’m just sad that the experiment is over. And it was such a good experiment, too. So elegant. So unique. Darwin never knew.”
Harding said to Thorne, “I’m going to clean this out now. Hold his leg for me.” More loudly, she said, “What didn’t Darwin know, Ian?”
“That life is a complex system,” he said, “and everything that goes along with that. Fitness landscapes. Adaptive walks. Boolean nets. Self-organizing behavior. Poor man. Ouch! What are you doing there?”
“Just tell us,” Harding said, bent over the wound. “Darwin had no idea . . .”
“That life is so unbelievably complex,” Malcolm said. “Nobody realizes it. I mean, a single fertilized egg has a hundred thousand genes, which act in a coordinated way, switching on and off at specific times, to transform that single cell into a complete living creature. That one cell starts to divide, but the subsequent cells are different. They specialize. Some are nerve. Some are gut. Some are limb. Each set of cells begins to follow its own program, developing, interacting. Eventually there are two hundred and fifty different kinds of cells, all developing together, at exactly the right time. Just when the organism needs a circulatory system, the heart starts pumping. Just when hormones are needed, the adrenals start to make them. Week after week, this unimaginably complex development proceeds perfectly—perfectly. It’s incredible. No human activity comes close.
“I mean, you ever build a house? A house is simple in comparison. But even so, workmen build the stairs wrong, they put the sink in backward, the tile man doesn’t show up when he’s supposed to. All kinds of things go wrong. And yet the fly that lands on the workman’s lunch is perfect. Ow! Take it easy.”
“Sorry,” she said, continuing to clean his wound.
“But the point,” Malcolm said, “is that this intricate developmental process in the cell is something we can barely describe, let alone understand. Do you realize the limits of our understanding? Mathematically, we can describe two things interacting, like two planets in space. Three things interacting—three planets in space—well, that becomes a problem. Four or five things interacting, we can’t really do it. And inside the cell, there’s one hundred thousand things interacting. You have to throw up your hands. It’s so complex—how is it even possible that life ever happens at all? Some people think the answer is that living forms organize themselves. Life creates its own order, the way crystallization creates order. Some people think life crystallizes into being, and that’s how the complexity is managed.
“Because, if you didn’t know any physical chemistry, you could look at a crystal and ask all the same questions. You’d see those beautiful spars, those perfect geometric facets, and you could ask, What’s controlling this process? How does the crystal end up so perfectly formed—and looking so much like other crystals? But it turns out a crystal is just the way molecular forces arrange themselves in solid form. No one controls it. It happens on its own. To ask a lot of questions about a crystal means you don’t understand the fundamental nature of the processes that led to its creation.
“So maybe living forms are a kind of crystallization. Maybe life just happens. And maybe, like crystals, there’s a characteristic order to living things that is generated by their interacting elements. Okay. Well, one of the things that crystals teach us is that order can arise very fast. One minute you have a liquid, with all the molecules moving randomly. The next minute, a crystal forms, and all the molecules are locked in order. Right?”
“Right . . .”
“Okay. Now. Think of the interaction of life forms on the planet to make an ecosystem. That’s even more complex than a single animal. All the arrangements are very complicated. Like the yucca plant. You know about that?”
“Tell me.”
“The yucca plant depends on a particular moth which gathers pollen into a ball, and carries the ball to a different plant—not a different flower on the same plant—where it rubs the ball on the plant, fertilizing it. Only then does the moth lay its eggs. The yucca plant can’t survive without the moth. The moth can’t survive without the plant. Complex interactions like that make you think maybe behavior is a kind of crystallization, too.”
“You’re speaking metaphorically?” Harding said.
“I’m talking about all the order in the natural world,” Malcolm said. “And how perhaps it can emerge fast, through crystallization. Because complex animals can evolve their behavior rapidly. Changes can occur very quickly. Human beings are transforming the planet, and nobody knows whether it’s a dangerous development or not. So these behavioral processes can happen faster than we usually think evolution occurs. In ten thousand years human beings have gone from hunting to farming to cities to cyberspace. Behavior is screaming forward, and it might be nonadaptive. Nobody knows. Although personally, I think cyberspace means the end of our species.”
“Yes? Why is that?”
“Because it means the end of innovation,” Malcolm said. “This idea that the whole world is wired together is mass death. Every biologist knows that small groups in isolation evolve fastest. You put a thousand birds on an ocean island and they’ll evolve very fast. You put ten thousand on a big continent, and their evolution slows down. Now, for our own species, evolution occurs mostly through our behavior. We innovate new behavior to adapt. And everybody on earth knows that innovation only occurs in small groups. Put three people on a committee and they may get something done. Ten people, and it gets harder. Thirty people, and nothing happens. Thirty million, it becomes impossible. That’s the effect of mass media—it keeps anything from happening. Mass media swamps diversity. It makes every place the same. Bangkok or Tokyo or London: there’s a McDonald’s on one corner, a Benetton on another, a Gap across the street. Regional differences vanish. All differences vanish. In a mass-media world, there’s less of everything except the top ten books, records, movies, ideas. People worry about losing species diversity in the rain forest. But what about intellectual diversity—our most necessary resource? That’s disappearing faster than trees. But we haven’t figured that out, so now we’re planning to put five billion p
eople together in cyberspace. And it’ll freeze the entire species. Everything will stop dead in its tracks. Everyone will think the same thing at the same time. Global uniformity. Oh, that hurts. Are you done?”
“Almost,” Harding said. “Hang on.”
“And believe me, it’ll be fast. If you map complex systems on a fitness landscape, you find the behavior can move so fast that fitness can drop precipitously. It doesn’t require asteroids or diseases or anything else. It’s just behavior that suddenly emerges, and turns out to be fatal to the creatures that do it. My idea was that dinosaurs—being complex creatures—might have undergone some of these behavioral changes. And that led to their extinction.”
“What, all of them?”
“It just takes a few,” Malcolm said. “Some dinosaur roots in the swamps around the inland sea, changes the water circulation, and destroys the plant ecology that twenty other species depend on. Bang! They’re gone. That causes still more dislocations. A predator dies off, and its prey grow unchecked. The ecosystem becomes unbalanced. More things go wrong. More species die. And suddenly it’s over. It could have happened that way.”
“Just behavior . . .”
“Yes,” Malcolm said. “Anyway, that was the idea. And I had this nice thought that we might prove it. . . . But now it’s finished. We have to get out of here. You better tell the others.”
Thorne clicked on the radio. “Eddie? It’s Doc.”
There was no answer.
“Eddie?”
The radio crackled. And then they heard a noise that at first sounded like static. It was a moment before they realized it was a high-pitched human scream.
